Dick, seriously champ you have to exorcise this "ATCs are resistant to change" mentality, it colours your judgment and reduces your credibility. ATCs are NOT resistant to change, if they were the system would still be using shrimp-boats on a bright screen display. The fact of the matter is that ATC is a constantly changing environment, if you are not ammenable to the change you wont have a job. Add this to the fact that once a mandated change has been "ordered" it's the ATC's who actually implement it, including all the studies and training material required. Just because ATC's are resistant to your ideas doesnt mean they are resistant to all ideas. Stop being such a victim and suck it in.
